Not only when advertising material in question is substituted or only existent in physical form but also when it comes to other tracking codes, the capability of the tags for HTTPS always has to be ensured.

• Every ad interaction has to be SSL compatible (“HTTPS”). All servers included have to be fully SSL certified.
• The ad tag should know automatically, that it is being called by the HTTP or HTTPS protocol. It should also automatically adjust its reaction, so it is SSL compatible
• A provider has to receive a special certification in order to publish ads within SSL compatible publisher inventory.

Impression Pixels / Tracking Pixels
Please be aware of the fact that every delivery of physical advertising material containing an impression pixel has to be specified for both HTTP and HTTPS. This also includes other tracking pixels.
